Abstract: Generally, waste activated carbon generated from water treatment facilities is buried, causing adverse effects on the soil environment, and as land fill sites are increasingly saturated, finding an appropriate alternative is difficult. The thermal regeneration method, which is used as a way to regenerate waste activated carbon, presents many difficulties such as air pollution, low regeneration yield, increased operating costs, inconvenient management, etc. and hence is too problematic to be employed to regenerate and reuse waste activated carbon. As such, the regeneration of waste activated carbon gives rise to many environmental problems such as high regeneration costs, reduced performance of regenerated activated carbon, air pollution problems, and land fill sites for final disposal. To address the aforementioned problems, the present invention provides a method of reusing waste activated carbon generated from water treatment sites as solid fuel as an eco-friendly alternative fuel, and more specifically, a method in which waste activated carbon and coffee waste are mixed in an appropriate ratio, and further mixed with a caking additive and molded to produce economical eco-friendly briquettes with high calorific power and solid fuels in a pellet form appropriate for an intended purpose of use.
